PBOJ'EGTING APPARATUS FOIt MOTION-PICTURE MACHINES.

Specification of Letters Patent.

Application filed July 28, 1914. Serial No. 852,645.

To all whom it may concern Be it known that'I, SHERRY MOAULEY, a citizenof the United States, resident of Atlanta, in the county of Fulton andState of Georgia, have made a certain new and. useful Invention inProjecting Apparatus for Motion-Picture Machines; and I declare thefollowing to bee. full, clear, and exact de- "scriptionof the same, suchas will enable others skilled in the art to which it appertains to makeand use the invention, reference being bad to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

Figure 1 is a side view of the invention as applied- Fig. 2 is a centralvertical section of the invention, with the mirrors in inactiveposition. Fig. 3 is a similar view with the mirrors turned to activeposition. Fig. 4 is a side view of the invention as applied, partlydiagrammatic, showing the screen, and the paths of the rays of light indotted lines. I

The invention has relation mainly to motion picture apparatus, havingfor its object the provision of improved means whereby a change from onepicture to another and radically different picture, located the oneabove the other (as for instance the change of a pumpkin into a chariot,or a man into an animal) may be eflected, the one picture dissolving, asit may be termed, into the other.

The invention consists in the novel conhereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2designates the lamp house of a motion picture machine, to whichthe'invention is shown as applied, the casing 3 of the dissolver beingusually substituted for the cone of said lamp house,

and including a lower chamber 4, through which the'light rays of thelamp normally pass in straight unobstructed manner, as

9 and 10 designate parallel reflectors,

struction and combinations of parts, as

out

ally. through inclined forming normally the upper and lower walls ofsaid lower chamber, said reflectors being each hinged in rear at 11 andhaving a link connectlon 12 to move in parallel relation. -When thelower picture is to be changed or dissolved into the upper picture, thereflectors are moved, usually by a crank handle 13 upon the pivot rod ofone of the reflectors, until they assume an angle of about forty-fivedegrees, being still in parallel; The light rays from the lamp enteringthe open rear end 140i the lower chamber will now strike the interposedlower reflector, being then reflected straight upwardly to the upperreflector, and thence straight out through the upper picture to thescreen, as shown by the arrows, the lenses for enlargement beingsuitably located with relation to the pictures so that Patented Mar. 30,1915.

the enlargements of the two pictures thus successively thrown upon thescreen will substantially register, and, the light being gradually cutoff from the lower picture by the interposed lower reflector andgradually given to the upper picture by the movement of the reflectors,the illusion of the change is 1 complete.

Thelower picture may be located upon a slide, as in a stereopticon, andthe upper picture upon a similar slide. Or the lower picture may be oneof a series upon a moving picture film, passing'through the lowerpassage.

What I claim is: 1. In projecting apparatus, a means for dissolving oneimage into another, consisting of a pair of normally inactive oppositemirrors located at the sides ofthe normal path of the lightrays from alamp of said apparatus, and means for movin said mirrors in parallelthrough incline tions to gradually bar an increasing number of said raysfrom their first path and reflect them along another and diiferent path.

2. In projecting apparatus, a means fordissolving one image intoanother, consisting of a pair of normally inactive opposite pivotedparallel mirrors having a link connection and located at the top andbottom of the normal path of the light rays from a lamp of saidapparatus, and a crank arm upon the pivot rod of one of said mirrors formoving the mirrors in parallel graduplisli'the, iresult stated.

posi-' v11o positions to 'accom- I 3. In rojecting apparatus, thecombination wit a lamp house having a lamp and a condenser lens, of anattachment including a casing provided with a lower chamber in line withsaid condenser lens and in the normal path of the rays from said lamp,and an u per chamber, transverse passages in line with the upper andlower chambers and designed for location of the pictures or films, apair of normally inactive mirrors located at the sides of the lowerchamber, and hand operated crank means for moving said mirrors inparallel gradually through inclinedpositions to accomplish the resultstated. v

In testimony whereof I aflix my signature, in presence of two witnesses.

SHERRY McAULEY.
